CA 2386844

A liner (10) is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner (10) is advanced through the narrowed region in a collapsed position. A stent (26) is then advanced through the liner (10) and expanded to open the narrowed region. The liner (10) may also have an anchor (12) which expands an end of the liner (10) before the stent (26) is introduced.

On fait avancer une chemise à travers une région rétrécie d'un vaisseau tel que l'artère carotide interne. Cette chemise est avancée en position affaissée. On fait avancer ensuite, à travers la chemise, une endoprothèse qui est étendue de manière à ouvrir la région rétrécie. La chemise peut aussi comporter un dispositif d'ancrage qui étend une extrémité de la chemise avant introduction de l'endoprothèse.
